Definitions
- the present disclosure is directed to co-located inkjets and particle delivery systems and methods related to such devices.
- Inkjet printing systems may use particles in a liquid ink to give the ink various properties. Particles may be added to the liquid ink to change properties of the liquid such as color, surface texture, opacity, luminescence, and/or other properties.
- Embodiments described herein involve a printing apparatus comprising a liquid ejector configured to eject liquid droplets towards a medium.
- a particle delivery device is configured to deliver particles to the medium. The particles are configured to combine with at least some of the liquid droplets and change at least one property of the liquid droplets.
- the particle delivery device is configured to deliver the particles after or substantially simultaneously as the liquid droplets are ejected.
- a curing device is configured to cure the combination of the liquid droplets and the particles onto the medium.
- a controller is configured to independently control the liquid ejector and the particle delivery device.
- Embodiments described herein involve a method that includes ejecting liquid droplets towards a medium. Particles are delivered to the medium at substantially a same time as or after the liquid droplets are ejected. The particles are configured to combine with least some of the liquid droplets on the medium and change at least one property of the liquid droplets. The ejection of the liquid droplets and the delivery of the particles are independently controlled. The combination of liquid droplets and the particles are cured onto the medium
- FIGS. 1A and 1B illustrate a liquid ejector and a particle delivery device in accordance with various embodiments described herein.
- FIG. 2 illustrates an example in which the liquid droplets and the particles are configured to combine before the liquid droplets or the particles reach the medium in accordance with embodiments described herein;
- FIG. 3 illustrates a more detailed view of a liquid droplet ejection device in accordance with embodiments described herein;
- FIG. 4A illustrates a particle delivery system utilizing a propellant to eject the particles in accordance with embodiments described herein;
- FIG. 4B illustrates a particle delivery system using a fluidized bed in accordance with embodiments described herein;
- FIG. 5 illustrates an example in which the liquid ejector is disposed within a particle ejector in accordance with embodiments described herein;

- Inkjet printing systems may use solid materials in a liquid ink to give the ink various properties.
- the solid materials may be configured to change at least one property of the liquid.
- the solid materials may change the color, surface texture, opacity, luminescence, and/or other properties of the liquid. Saturated colors such as white may be more easily achieved by using a high proportion of solid materials to liquid.
- chemical properties of the liquid may be controlled using powder treatments, for example. Adjusting the surface ratio of solids to liquid may be useful for three dimensional solid surfaces and/or controlling the light scattering properties of surfaces. According to various embodiments, having a high ratio of particles to liquid may allow for a higher level of chemical resistance and or other types of wear resistance. Light scattering properties of the medium can also be controlled by controlling the ratio of particles to liquid.
- a large solid fraction may be difficult to jet as the viscosity becomes too large.
- the large solid fraction may be challenging to keep in suspension within the liquid. Having a separate solid ejection device in addition to an inkjet print head and/or other liquid ejection device may be useful for overcoming these difficulties.

- the angle, ⁇ 2 , for the liquid ejector may be in a range of roughly 0-70 degrees.
- the angle, ⁇ 2 for the particle delivery device may be at an angle in a range of about 0-70 degrees, for example.
- at least one of the liquid ejectors may be at a different angle with respect to the longitudinal axis as at least one other liquid ejector.
- all of the multiple liquid ejectors are disposed at substantially the same angle with respect to the longitudinal axis.
- the system may have more than one liquid ejector or particle delivery device.
- FIG. 1B shows an example having two liquid ejectors 120 , 122 .

- FIG. 2 illustrates an example in which the liquid droplets 230 , 235 and the particles 240 are configured to combine before the liquid droplets 230 , 235 or the particles reach the medium 260 .
- the resulting combination 250 of the particles 240 and the liquid droplets 230 , 235 is then transferred to the medium 260 .
- the combination of the particles and the liquid droplets creates a chemical reaction before the mixture reaches the medium. For example, alginate and Ca solutions or two part epoxy resins cause a change from liquid to solids.
- the particles 240 and the liquid droplets 230 , 235 may be oppositely charged to promote fusion to one another.
- the particles 240 may be positively charged before exiting the particle delivery device 210 and the liquid droplets 230 , 235 may be negatively charged.
- a tribo-charged surface such as polytetrafluoroethylene (PTFE) may be used to charge the particles 240 and/or the liquid droplets 230 , 235 . While the example shown in FIG. 2 has positively charged particles 240 and negatively charged liquid droplets 230 , 235 , it is to be understood that the particles 240 may be negatively charged and the liquid droplets 230 , 235 may be positively charged.
- liquid droplets from one of the liquid ejectors may be configured to have a charge while liquid droplets from other liquid ejectors are not charged or have a different charge. In some cases, all of the liquid droplets from the multiple liquid ejectors have the same charge.
- FIG. 3 illustrates a more detailed view of a liquid droplet ejection device.
- the device includes a reservoir 310 that holds the liquid. The liquid then passes through an orifice 320 into cavity 330 .
- Each ejector 300 includes an actuator, such as piezoelectric transducer (PZT) actuator 350 , that can be electrically activated to induce a pressure wave within the ejection chamber cavity 330 and nozzle 340 .
- the PZT actuator 350 is activated by a signal from a controller.
- the controller provides a signal that activates the PZT 350 to generate a pressure wave in the ejection chamber cavity 330 sufficient to cause ejection of an ink drop through the nozzle 340 .
- FIG. 4A A particle ejector system is illustrated in FIG. 4A .
- the system comprises a body 440 into which is formed a Laval-type expansion pipe 430 .
- a carrier such as air, CO 2 , etc. is injected at a first proximal end 405 of body 440 to form a propellant stream within pipe 430 .
- a plurality of channels 410 , 412 , 414 , 416 are also formed in body 440 . These channels 410 , 412 , 414 , 416 are configured to deliver a material, such as a powder, into the propellant stream. Control of the introduction of material from channels 410 , 412 , 414 , 416 is achieved, for example, by way of an electrostatic gate 420 , 422 .
- FIG. 4A illustrates a particle ejector utilizing a propellant
- an electrostatic deposition technology may be used to eject the particles.
- An electrostatic field may be applied to charged particles causing the particles to be ejected from the device.
- the particles are ejected without precision as to location.
- the particles may be ejected over the whole or a large portion of the medium.
- the particles may be configured to only coat the portions of the medium that contain the liquid droplets.
- a fluidized bed is used to deliver particles as shown in FIG. 4B .
- Creating a fluidized bed can be accomplished by adding a gas 487 to a container 480 with the particles 475 .
- a carrier gas such as nitrogen can be added to the container 480 to levitate and transport the particles 475 .
- the gas 487 can impart a charge to the particles 475 . This can be achieved through triboelectric charging and/or electric field charging, for example.
- the fluidized bed is used to elevate the particles 475 and an airjet may be used to transport the elevated particles into an airstream.
- the particles 475 then adhere to liquid droplets 490 ejected from a liquid ejector onto a medium 485 .
- the combination of the liquid droplets and the particles may be cured to fix the combination of liquid droplets 490 and particles 475 onto the medium 485 .
- an airjet is used to remove 477 excess particles before and/or after the curing process.
- the airjet used to transport the particles into the airstream may be the same or different than the airjet used to remove excess particles.
- This particle dispersment technique can be combined with inkjet or other types of liquid ejector systems.
- the liquid ejector is within the particle ejector.
- the liquid ejector may be inside of a particle ejector such that the particles surround the liquid droplets as the droplets are ejected from the device.
- FIG. 5 illustrates an example in which the liquid ejector is within the particle ejector.
- the liquid ejector includes a reservoir 530 that holds the liquid. The liquid then passes through an orifice 560 into cavity 562 . The liquid droplets are ejected through the nozzle 565 .
- the liquid in the liquid ejector device is bound by walls 570 .
- a particle ejector Surrounding the liquid ejector is a particle ejector.
- Particles 540 are moved along the device via a propellant, for example.
- the particles and the propellant are disposed between the walls 570 of the liquid ejector and walls 510 of the particle ejector.
- the particles move along the device until exiting the device at the nozzle 535 .
- the resulting output from the combined liquid and particle device is a combination of the liquid droplets 530 surrounded by the propellant stream 545 .
- the particles 545 and the propellant create a laminar flow around the exit point of the nozzle 535 so the liquid droplets 530 are entrained inside the air stream.
- the propellant surrounding the liquid droplets may increase the precision of the droplet placement allowing more distance between the liquid ejector and the medium than in a system having only a liquid ejector.
- FIG. 6 illustrates a system 600 that shows a controller 630 that is configured to independently control the particle delivery device 610 and the liquid ejector 620 .
- the controller 630 can control when the delivery device 610 is activated.
- the controller 630 may be configured to eject a certain ratio of solid to liquid. This ratio may be capable of being changed depending on the application.
- the controller 630 may control the timing of the ejection of the liquid droplets and/or the particles.
- the controller 630 is configured to spatially vary the ratio of the liquid droplets to the particles on a surface of the medium.
- first portion of the medium having a first property may have a surface texture that differs from the surface texture of the second portion of the medium.
- some portions of the medium only have liquid droplets while other portions have the combined liquid and solid combination.
- adjusting the solid ratio increases the viscosity of the mixture of solid and liquid and can help control the impact size and adhesion at the surface of the medium.
- the controller may also be configured to control a curing device 640 that cures the combination of liquid droplets and particles onto the medium.
- FIG. 7A illustrates a printing system that incorporates a liquid ejection system and a particle delivery system.
- the liquid ejector system 705 includes three separate liquid ejectors.
- Each liquid ejector includes an ink course 710 , 712 , 714 , a PZT actuator 730 , 732 , 734 and an array of nozzles 745 , 747 , 749 disposed in a nozzle plate 740 .
- Each of the separate liquid ejectors may be configured to eject liquid having a different property.
- each liquid ejector system may be configured to eject liquid having a different color.
- the separate liquid ejectors are configured to eject liquid droplets 760 at different locations on the medium 750 . While the system illustrated in FIG. 7A shows three separate liquid ejectors, it is to be understood that there could be a different number of liquid ejectors.
- the liquid ejectors may be configured to eject low viscosity liquids such as inks, UV gels, binders, and/or any combination in high resolution patterns onto the medium 750 .
- a particle delivery device is configured to deliver particles 775 , e.g., a powder, onto the medium 750 such that the particles 775 coat the liquid droplets 760 on the medium 750 , but do not coat areas of the medium 750 that do not include liquid droplets 760 .
- the medium 750 may be configured to move in the direction of arrow 790 as the liquid droplets 760 and/or the particles 775 are being delivered to the medium 750 .
- the particle delivery device uses a propellant to eject the particles 775 towards the medium 750 .
- the particles 775 are to be delivered to the medium 750 using a fluidized bed 752 and/or an electrostatic cloud, for example.
- the fluidized bed 752 shown in FIG. 7B can be created by adding a gas 754 causing the particles to levitate and to combine with the liquid droplets 760 on the medium 750 .
- the particles 775 are delivered to the medium 750 by pouring the particles 775 onto the medium 750 .
- the coated liquid droplets are cured to adhere the combination onto the medium 750 .
- the combination may be cured using a UV curing process such as UV cross-linking.
- a thermal curing process such as a thermal curing process, a chemical reaction curing process, and/or a phase change curing process.
- the curing process may involve solvent evaporation the combination of liquid droplets 760 and particles 775 .
- the combination of liquid droplets 760 and particles 775 may be solidified through the use of UV for UV polymers, solvent evaporation in the case of aqueous inks, cooling in the case of phase change materials and/or through the use of chemical curing agents.
- the liquid droplets 760 may be configured to resist drying until a curing process takes place.
- An optional airjet 795 may be used to remove excess particles from the medium 750 before or after the curing step. It is to be understood that any combination of curing processes may be used to cure the combination of liquid droplets and particles.
- FIG. 8 illustrates a process for using a liquid ejection device with a particle delivery device in accordance with embodiments described herein.
- Liquid droplets are ejected 810 towards a medium.
- Particles are delivered 820 to the medium at substantially a same time as or after the liquid droplets are ejected.
- the particles are configured to combine with at least some of the liquid droplets on the medium and change at least one property of the liquid droplets. Ejection of the liquid droplets and the delivery of the particles are independently controlled.
- the combination of liquid droplets and particles are cured 840 onto the medium.
